The starter battery will last longer
Less chance of failer
IMO you should scrap the whole ez start and buy a pull start. I have been using a pull start on my Savage for a while, when I got my LST it had a roto start on it and if I keep the truck it's getting a pull start.
I used to think electric starters where the best thing on earth but now they are just a PITA and more crap to mess with.
